Question: One of the greatest problems in marketing research and other survey fields is the problem of nonresponse to surveys. In home interviews the problem arises when the respondent is not home at the time of the visit or, sometimes, simply refuses to answer questions. A market researcher believes that a respondent will answer all questions with probability 0.94 if found at home. He further believes that the probability that a given person will be found at home is 0.65. Given this information, what percentage of the interviews will be successfully completed?
